SPECIFICATION forming part of Letters Patent No. 448,174, dated March 10, 1891. Application filed May 25, 1889. Serial No. 312,068. (Specimens) To all whom it may concern.-

Be it known that we, FARMER ROOD VIL- LIAMS and GEORGE HOMER ORAM, citizens of the United States, residing at Beloit, in the county of Rock and State of Visconsimhave invented certain new and useful Improvements in Twine; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawing, and to the letters of reference marked thereongvhich form a part of this specification.

Our invention relates to twine or cord, especially to that made of paper; audits object is to provide farmers and others with a strong, cheap, durable twine for binding grain suitable for use in self-binding harvesters and a satisfactory substitute for the flax or hemp twines now generally used for that purpose.

Our invention consists of a twine or cord made of paper, Waterproofed, waxed, and compressed, as hereinafter set forth and claimed.

The drawing represents a piece of our twine, one end being untwisted and the whole illustrating the various steps in the process by which itis made.

The paper which we prefer to use is made of chemical fiber, tobacco-stems, rags, woodpulp, and rope-stock, though any tough strong" paper may be used. It is prepared in long narrow strips A, and is first passed through a bath of any suitable waterproofing material-such, for instance, as a mixture of beeswax, tallow, pinc-tar,linseed-oil, and an acid solution.

By accomplishing the waterproofing of the paper before it is twisted into twine we insure the subjection of the entire strip to the action of the bath, which cannot be the case if the twine is waterproofed after being twisted. The strip of waterproofed paper B is twisted by suitable mechanism into a rope or cord 0 of any desired diameter. It is then treated to a coating of wax D, such as beeswax or paraffine, the coating being of greater or less thickness, as circumstances may require. This fills up all the irregularities in the surface and smooths down any projecting fibers or ragged edges of the paper. The waxed twine is finally subjected to the action of suitable compressing devices, such as a pair of grooved rollers, whereby it is reduced to a uniform size, hardened, and polished, as shown at E. In this condition it is reeled up or otherwise packed for shipment to purchaser-s.

Our waterproofed, waxed, and compressed paper twine is strong, and durable and an exoellent substitute for the twines now used by farmers for binding grain. It runs smoothly through the mechanism of a bi riding-machine, and will not rot or break under ordinary circumstances. So far as we are aware no one has heretofore produced such an article; and hence,

Having thus described our invention, what we claim, and desire to secure by Letters Patent, iS

1. A compressed binding-twine for harvesters, composed of waterproofed paper, substantially as described.

2. Twine composed of waterproofed paper and coated with wax, substantially as described.

3. Twine composed of Waterproofed paper coated with wax and compressed, substantially as described.

4. A paper twine coated with wax, substantially as described.

5. A paper twine coated with wax and compressed, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
